Specification of Letter: Patent. Patented flgv, 28, 1911,

Application filed June 29, 1911 Serial No. 638,085.

particularly to that type of machine illustrated in my prior applicationSerial No. 612,566, filed March 6,.1911.

The main features of the machine, as far as the slitting and rewindingoperations are concerned, are substantially the same .as in the machineillustrated in the application above referred to.

The main object of my present invention is to facilitate the subdivisionof a tube u on which the material is rewound, the sections into whichthe tube is subdivided corresponding in length to the width of theseparate strips of rewound material, so that a long tube-may be placedin the machine, cut

to the proper lengths, and thematerial rewound, each strip of rewoundmaterial being upon a separate section of the tube.

A further object of my invention is to utilize the pressure roller ofthe machine which normally engages with the material during therewinding, as a means for forcing the tube cutters into the tube.

A still. further object of my invention is to facilitate the raising andlowering of the pressure roller during the placing of the tube cuttersor the removal of the completed rolls and to permit the locking of thepressure roller in raised position.

The invention consists in the arrangement and combination or partshereinafter particularly described and pointed out in the claims-Reference is to be had to the accompanying drawings, which form a partof this specification'and in which similar reference characters indicatecorresponding parts in the different views. I

Figure 1 is an endview of a machine constructed in accordance with myinvention; Fig. 2 is a vertical section through the upper centralportion of the machine showing the tube cutters in operative position;Fig. 3

is a top plan view of a portion of the machine, showin the arm raisingmechanism; Fig. 4 is a sectlonal detail of a portion of the armraisingmechanism; Fig. 5' is a top plan View of a portion of the tube cutters;and Fig. 6 is a face view of a portion of the machine showing the tubecutters.

In this machine illustrated, there is employed a main frame 10, servingto support a roll A of .paper or other similar material to be unwound,slitted and rewound and also serving to support guide rollers 11, rotarycutters 12 and 13, a reel 14 and friction rollers 15. The paper passesfrom the roll over certain of the guide rollers, thence between thecutters and eventually on to the reel. The reel is supported by twofriction rollers 15, which are rotatedin the same di rection, and theroll of rewound material on the reel is held down by a pressure roller16 which is also positively driven. The pressure roller is movablevertically and is carried by the arms 18 pivoted to two pivoted arms 19.

.I do not claim in this ap lication any patentable features in thedetails of the ma chine so far described. The machine serves to cut thepaper into strips of any desired width, and a special feature of mypresentimprovements relates to a se aration of the tube upon which thematerial is rewound, into sections. In carrying out this part of myinvention, I place a tube 13 on to the reel 14, the tube beingpreferably of paper and constructed in the same manner as an ordinarymailing tube. In the rear portion of the machine I provide atransversely extending rod, and pivoted to this rod, are a plurality ofarms 21 adjustable lengthwise of the rod and each adaptedto be locked tothe rod by a set screw or other similar device. Each arm has journaledupon the under side thereof a rotary cutter 22, which, when the arms areswung forward, will engage with the upper side of the tube upon thereel. The arms 21 are adjusted to such positions along the rod 20 thatthe cutters 22 will be at the same distance apart as the main pairs ofcutters for the paper. The cutters 22 come directly upon the upper sideof the tube and beneath the-pressure roller 16, and each arm has a seat23 for the roller.

In using my improved machine, a tube tent for which the cutters mayenter the tube and to prevent them from being dulled on the reel 14, thetwo end arms 21 may each be provided with small rollers 24, as' shown inFig. 6, so as to engage with the tube upon opposite sides of the cutterand limit the cut of the latter. When the cutting operation is finished,the pressure roller is ralsed and the arms 21' thrown back to theposition shown in doi ted lines in Fig. 1. Here they may rest against asmall cross bar 25.

- To facilitate the raising and lowering of the pressure roller, Iprovide the arm- 19 with a segment 26 and mount a pinion 27 in mesh withthis segment. The pinion is mounted on a stub shaft 28, which shaft alsocarries a wheel 29. The wheel is rotated by means of a handle 30, whichextends forwardly to the front part of the machine, so as to be withineasy grasp ofthe operator. The handle may be secured to the wheel at anyone of the plurality points by means of sockets 31 in the wheel and itmay be locked in any socket by means of suitable screws 32. By pullingdown on the front end of the handle, the pressure roller and arm 19 maybe readily raised the required distance, inasmuch as the pinion has asmaller radius than the segment, and the handle 30 is of greater lengthand greater leverage than the arm 19. The handle 30 is, of course, usedfor raising the pressure roller'to permit the removal of the rolls ofrewound material. For locking the pressure roller in raised position, Iprovide a catch 33 mounted in a socket 34 carried by the main frame. Thehandle may be sprung out and slipped beneath the catch, or the 'catchmay be longitudinally movable within thesocket. I

Various changes may be made in the details of construction of myimproved machine without departing from the spirit of my invention.
